An anonymous file sharing service Way to setup Django project with nginx + gunicorn (python 3 and Django > 2.0) Ubuntu,

1. sudo apt-get update sudo apt-get install python3-pip python3-dev libpq-dev nginx
2. To get the other requirments of the project ready, We would recommend to use a virtual enviroment bash sudo -H pip install --upgrade pip sudo -H pip install virtualenv
3. Make a new directory or git clone [your exixting repo]
4. Go to your directory by cd /yourproject Now we create a virtual Enviroment virtualenv yourenv If python3 is the only python version on your system the enviroment will be made by python3 else your need to specify the path of the python version you want the virtual enviroment to be virtualenv -p /path/to/any/bin/python yourenv This will create a directory called yourenv within yourproject directory. We can use this to install and configure
5. source yourporject/bin/activate (to activate virtualenv) pip install django gunicorn (Regardless Python version you are using, when in virtual environment
   you should use the pip command not 'pip3'
6. Adjusting Project Settings Start by Changing the ALLOWED_HOSTS settings , this list tells the django instance about the host that can connect nano ~/yourproject/yourporject/settings.py ALLOWED_HOSTS = ['your_IP_or_domain', '.example.com', . . .]
7. Check the static files directory settings so that Nginx can handle these requests STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static/')
8. Now its time to makemigrations so that Django can make nesscerry migrations based on models into your database python manage.py makemigrations python manage.py migrate *which is responsible for applying and unapplying migrations. Make sure from step 5 you are in your virtualenv Now we collect all the static content in the directory we configured above python manage.py collectstatic

9.At this step your are basically done with your Django app only thing left is firewall rules and Nginx setup Create firewall rule for port:8000 (can be anything your desire) Now we test the django application by running the server

python manage.py runserver 0.0.0.0:8000

*this will run the server on port 8000 the ip will be the static ip of the server

you can check the app in your web browser by http://your_domain_or_IP:8000 If everything works as intended your will see ur index page or the default index djnago page Ctrl+c to exit server In production it is recommended to serve the application by a server not django's internal server The Gunicorn "Green Unicorn" is a Python Web Server Gateway Interface HTTP server gunicorn uses the WSGI application

WSGI: A Python spec that defines a standard interface for communication between an application or framework and an application/web server. This was created in order to simplify and standardize communication between these components for consistency and interchangeability. This basically defines an API interface that can be used over other protocols.

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
User=yourubuntuusername
Group=www-data
WorkingDirectory=/home/yourubuntuusername/yourproject
ExecStart=/home/yourubuntuusername/yourproject/yourenv/gunicorn --access-logfile - --workers 3 --bind unix:/home/yourubuntuusername/yourproject/yourproject.sock yourproject.wsgi:application

[Install]
WantedBy=multi-user.target

Service file is complete save and close it now. now lets start the service sudo systemctl start gunicorn sudo systemctl enable gunicorn To check if the configuration is correct we can check the presence of .sock file (socket) ls /home/yourubuntuuser/yourproject sudo systemctl status gunicorn --to check the gunicorn status If the status inticate an error check the gunicorn logs sudo journalctl -u gunicorn If you make changes to the /etc/systemd/system/gunicorn.service run the following commands it is required to do this sudo systemctl daemon-reload sudo systemctl restart gunicorn 12.After setting up gunicorn now we nned to setup Nginx to route the traffic sudo nano /etc/nginx/sites-available/yourproject

     server {
    listen 80;
    server_name _domain_or_IP;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/yourubuntuuser/yourproject;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/yourubuntuuser/yourproject/yourproject.sock;   
          }
     }

save and close the file when you are finished 13.Link the above file

`sudo ln -s /etc/nginx/sites-available/yourproject /etc/nginx/sites-enabled`

`Test Nginx config `

`sudo nginx -t`

If no errors restart the server by typing sudo systemctl restart nginx 14.Now we need to traffic are contents to port 80 insted to 8000' Delete the previously created open port sudo ufw delete allow 8000 Allow Nginx full control sudo ufw allow 'Nginx Full'

Configuration of SSL 1.
